Characterization and Cooled Storage of Semen from Corn Snakes (Elaphe Guttata)
Journal of Zoo and Wildlife Medicine 38(1): 7–12, 2007 Copyright 2007 by American Association of Zoo Veterinarians CHARACTERIZATION AND COOLED STORAGE OF SEMEN FROM CORN SNAKES (ELAPHE GUTTATA) Brooke M. Fahrig, M.S., Mark A. Mitchell, D.V.M., M.S., Ph.D., Bruce E. Eilts, D.V.M., M.S., Dipl. A.C.T., and Dale L. Paccamonti, D.V.M., M.S., Dipl. A.C.T. Abstract: The phylogenetic order Squamata has many representatives that could beneﬁt from the use of semen preservation as a tool for assisting conservation. To date, few studies have been made evaluating the potential for collecting and preserving semen from snakes. The objectives of this study were to characterize semen parameters of the corn snake (Elaphe guttata), including appearance, volume, concentration, sperm motility, and sperm morphology, and to determine the longevity of corn snake sperm motility stored at 4ЊC. Single semen samples were collected from 22 adult corn snakes. The appearance of the corn snake semen was generally cloudy, and the color was white to tan. Corn snake spermatozoa initially exhibited a median motility of 92.5%. Corn snakes were found to produce small- volume ejaculates (median 0.01 ml). However, the overall concentration of the snake ejaculate was high (x¯ ϭ 852 ϫ 106 Ϯ 585 ϫ 106 spermatozoa/ml). Morphologically, a mean of 75.7 Ϯ 9.3% of the sperm cells in an ejaculate were normal. Snake ejaculate with a white appearance had signiﬁcantly higher sperm concentrations (x¯ ϭ 1,859 ϫ 106 Ϯ 1,008 ϫ 106 sperm cells/ml; F ϭ 15.74, P ϭ 0.001) than tan ejaculates (x¯ ϭ 601 ϫ 106 Ϯ 439 ϫ 106 sperm cells/ml).

Description The American corn snake is an attractive reptile that is primarily nocturnal and highly variable in colour. Most adults display vivid reddish or orange blotches edged in black, on a grey or orange background. The colour intensifies with age. The snake reaches its adult length of 1–1.5 m within 3–5 years. Albino or light-coloured specimens are readily available in the American and European pet trade. The colouration pattern on the snake’s underside is similar to a variety of multi-coloured, ornamental corn. In its native region, the American corn snake lives in dry fields where it hunts for small mammals (e.g. mice), reptiles and insects. The snake is harmless to humans but will strike if disturbed to scare off predators. American corn snakes are constrictors, wrapping one or two coils around their prey and squeezing until the victim suffocates. Pest risk The American corn snake is a prohibited invasive animal under the Biosecurity Act 2014.

Constrictor Snake Incidents
constrictor snake incidents Seventeen people have died from large constrictor snake related incidents in the United States since 1978—12 just since 1990—including one person who suffered a heart attack during a violent struggle with his python and a woman who died from a Salmonella infection. Scores of adults and children have been injured during attacks by these deadly predators. Children, parents, and authorities are finding released or escaped pet pythons, boa constrictors, and anacondas all over the country, where they endanger communities, threaten ecosystems, and in many cases suffer tragic deaths. Following is a partial list of incidents, organized by various categories, involving constrictor snakes that have been reported in 45 states. Contents Read more Dangerous incidents Children and teenagers attacked or sickened by constrictor involving constrictor snakes snakes skyrocket Four babies sleeping in their cribs, as well as three other children have been squeezed to death by large constrictor snakes. Youngsters have 3 been attacked while playing in their yards, compressed to the point of unconsciousness, nearly blinded when bitten in the face, and suffered numerous other painful, traumatic, and disfiguring injuries. 34 incidents. Adults, other than the snake owner or caretaker, attacked or sickened by constrictor snakes Unsuspecting people have been attacked by escaped or released constrictor snakes while tending to their gardens, sleeping in their beds, 8 or protecting children and pets playing in their yards. One woman discovered an 8-foot python, who later bit an animal trapper she called, in her washing machine. 17 incidents.

St. Vincent National Wildlife Refuge Fish, Amphibian, Reptile and Mammal List
U.S. Fish & Wildlife Service St. Vincent National Wildlife Refuge Fish, Amphibian, Reptile and Mammal List photo: Debbie Hooper Eastern Diamondback Rattlesnake The St. Vincent NWR was established in 1968. The primary feature of St. Vincent NWR is St. Vincent Island, a 12,300 acre undeveloped barrier island, located in Franklin County, Florida, at the west end of Apalachicola Bay. The island is triangular in shape, nine miles long, four miles wide at the east end and gradually forms a point at Indian Pass on the west end. The island is characterized by ridge and swale photo: Monica Harrisphoto: topography American Alligator with well developed wetland and upland habitats. The refuge manages both salt and fresh water wetlands including several impoundments to provide a mix of wetland habitats. The size and shape of the island and variety of habitats provides for a diversity of wildlife species not typically found on barrier islands in the area. The refuge also administers an 86 acre mainland tract in Franklin County and the 45 acre Pig Island in St. Joe Bay, Gulf County. Endangered and Threatened Wildlife St. Vincent NWR provides refuge for several Federally and State listed endangered and threatened species. St. Vincent Island is an “Island Propagation Site” for the Red Wolf Recovery Program. A red wolf pair is allowed to raise pups on the island which are removed when they reach 18 months of age and shipped to North Carolina to help augment the photo: USFWS photo: Red Wolf wild population. Occasionally, West Indian manatees are seen in the waters around the refuge.

Corn Snake (Pantherophis Guttatus)
©ReptiFiles® — Where Better Reptile Care Begins — 2020 Corn Snake (Pantherophis guttatus) Difficulty: Easy Corn snakes are a semi-arboreal species of snake native to the southeastern United States, parts of Mexico, and the Cayman Islands. They are most often found in tropical and subtropical grasslands, savannas, and shrublands. They spend a good amount of time on the ground, but they are also proficient climbers. Corn snakes range from 3’ to 5’ long, with males tending to be smaller than females. Corn snakes typically have a lithe, slender body, with an orange and red pattern and a black-and-white belly. However, due to enthusiastic “morph” breeding in the reptile hobby, captive-bred corn snakes are now available in a diverse array of alternative colors and patterns. Corn snakes are some of the most popular pet snakes in the United States. They’re manageably-sized, are fairly tolerant of being housed in sub-ideal conditions, and generally tolerate human interaction well. Corn snakes are known to live up to 25 years with good care.
